Abstract

1294042 Sulphur-modified chloroprene polymers FARBENFABRIKEN BAYER AG 11 Jan 1971 [24 Jan 1970] 1168/71 Heading C3P Sulphur-modified chloroprene polymers and copolymers with up to 20 wt. per cent of another comonomer, the products having improved storage life, are prepared by aqueous emulsion polymerization in the presence of 0À1-2% sulphur and 0À5-5 wt. per cent of a watersoluble amine in which R 1 and R 2 each represent a C 2-5 hydroxyalkyl group and R 3 is a methyl group or as for R 1 and R 2 , the above percentages all being based on total monomer. Suitable amines are triethanolamine, tri-(isopropanol) amine and N.methyl-di-(isopropanol) amine. In examples, polychloroprene and a 97/3 chloroprene/2,3- dichloro-1,3-butadiene copolymer are prepared by conventional emulsion polymerization using potassium persulphate as catalyst, the reactions being stopped by adding phenothiazine and the products peptized by tetraethyl thiuram disulphide.
